Question

the perimeter of a rectangular card is 60 com. find the length and breadth which are in the ratio 2:1​

Answer 1

Answer:

18m

Step-by-step explanation:

Let the length of rectangle be x

Breadth = 12 m

perimeter = 60 m

2(l+b) = 60 m

x+12 = 30 m

x = 18 m

length of rectangle = 18 m

Answer 2

Answer:

Perimeter = 60 cm

Length = 2x

Breadth = 1x

2 (2x + 1x) = 60

2 (3x) = 60

6x = 60

x = 60/6

x = 10

Hence length = 2x

= 2 × 10 cm

= 20 cm

Breadth = 1x

= 1 × 10 cm

= 10 cm
